Growth of M. smegmatis in various nitrogen sources. Wild-type SMR5 and glnR deletion strain MH1 were grown in the presence of the indicated substances (10 mM final concentration) as sole nitrogen source. Standard 7H9 medium was used as positive control; 7H9 lacking any nitrogen source as negative control (7H9-N). (A) Putative nitrogen sources deduced from microarray results, (B) putative nitrogen sources used by closely related species.
